The invention discloses an interactive software signal and data fusion processing method, which comprises steps of calculating the maximal fuzzy speed, calculating a target radial speed, calculating a target channel number and judging correlation. On the basis of nearest neighbor correlation filtering algorithm, Doppler speed dimension characteristic information is added to participate in plot correlation, interactive comparison and judgment are carried out on target speed information in data processing and Doppler information provided by front signal processing, a correlated plot trace can be found out more accurately before a trace confirmation stage, accuracy of plot correlation is improved, and the problem of trace starting in a complicated environment is solved.
